1 I j SASHHOLDER.

' To aZZ whom it may concern: I

Be it known that I, SANFORDD. CASE, acitizen of the United States, residing at Brooklyn, in the county of Kings and State of New York,

have invented a new and useful Sash-Holder,

of which the following is a specification.

This invention 1s an mproved constructlon of sash-holder or device for holding the window-sash atany desired point, the object of .the invention being to provide a simple and easily raised and held in a raised position and can be lowered by the exertion of little force, thereby avoiding the use of complicated and expensive mechanisms for raising and lowering and holding the window-sash.

With these objects in view my invention consists, essentially, in the employment of a wire frame carrying rollers at the opposite ends and also spring brake-shoes which are adapted to engage the rollers, said brake-shoes serving to prevent the rotation of the rollers in a downward direction, but permitting said rollers to rotate in an upward direction, whereby the sash can be quickly and easily raised and held in a raisedposition and also by means of which the sash can be lowered bythe exertionof a small amount of force.

The invention consists also in certain details of construction hereinafter fully described, and pointed out in the claims. i

In'the drawings forming part-of this specification, Figure 1 is aperspective view showing my invention applied to one side of a window-sash; Fig. 2 is a sectional-view taken through the stile of said sash, theholding mechanism being shown in elevation; Fig. 3

is a face view of the device. Fig. L-is a detail perspective view showing the end of the frame with the roller and brake-shoe carried tened to this portion C is the spring-wire I specifi cation of Letters Patent. Application annary 6,1904. serial No. 187,906.

r frame D, which carries the rollers E at the op posite ends, said rollers being preferably constructed of leather, each roller being engaged by the spring brake-shoe F.

The rollers E engage the window-frame when the sash is arranged insaid frame, and owing to the positions of the spring brakeshoes with reference to the rollers it is obvious that the said rollers can rotate freely when the sash is moved upwardly, but will be held against rotation inthe reverse direction, and inasmuch as the frame carrying these rollers is a spring-frame they will be nor- -mally held against the window-frame, thereby holding the window-sash in its adjusted position. The sash,however, can be lowered by forcing the same downwardly, it being necessary to use only a sufficient amount of force to overcome the friction between the rollers and the window-frame, as the said rollers will slide upon the window-frame during such downward movement of the window-sash.

In order to provide as cheap, simple, and efficient construction as is possible, I form the spring-frame D from'a'single piece of spring- ,wire which is bent upon itself in opposite directions adjacent the center, as shown at D, and the oppositely-extending portions are bent again in theform of a U at D said bends,however, being in reverse directions, and at, the ends the wire is bent in the form of a rectangle, as shown at D the extreme end D serving as an axle upon which the roller E rotates. Staples G are employed for fastening the wire frame to the stile of the sash, said staples being driven overthe. bends .D and into the portion 0, thereby holding the spring-frame against movement at the center. The end portions of the frame, however, have a limited movement in the pockets 1 Eachbrake-shoe F is formed of a single piece .of spring metal, one end of which bears against its respective roller, the opposite end F being coiled around one of the parallel members of the bent portion D the intermediate portion of the spring brake-shoe being bent over the other parallel member of the bent portion D as most clearly shown at F in Figs, 4 and 5.

The upper brake-shoe projects inwardly and upwardly, while: the lower brakeshoe projects outwardly and downwardly, so that the upper brake-shoe engages the upper roller uponthe inner side and the lower brake-sh0e lIO the lower roller upon the outer side, and by this arrangement the window-sash can be quickly and easily raised and held in a raised position, inasmuch as the rollers rotate during the upward movement. When it is desired to lower the sash, however, these rollers are held against rotation by means of the spring brake-shoes, which act after the manner of pawls, and the rollers are therefore caused to slide upon the sides of the windowframe. The frame carrying the rollers being made of spring-wire, it will always hold the rollers in contact with the window-frame, and any unevenness or irregularities will be compensated for by the elasticity of the frame carrying the rollers.

It will thus be seen that I provide a cheap, simple, and efficient construction of sashholder capable of carrying out all of the objects hereinbefore mentioned.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a window-sash, having side pockets, the spring-wire frame formed from a single piece of wire secured to the sash, intermediate the pockets, the oppositely-extending portions being bent in the form of a U, rollers carried by the ends of the wire frame, and the spring-brakes secured to one side of each of the U-shaped bends, and extending over the other, and adapted to engage the rollers, carried by the frame, as set forth.

2. The combination with a window-sash having pockets as described, of the springwire frame, the leather rollers and the spring brake-shoes, the frame beingconstructcd from a single piece of wire bent upon itself in opposite directions adjacent the center, the oppositely-extending portions being bent in the form of a U, the ends of the wire being bent to form a rectangle and providing an axle for the rollers, the spring brake-shoes being connected to the frame at the U-shaped bend and adapted to engage their respective rollers, substantially as described.
